A
100
B
200
C
150
D
300
Verified step by step guidance1
Understand that each amino acid in a protein is coded by a sequence of three nucleotides in DNA, known as a codon or triplet.
Recognize that a protein with 100 amino acids requires 100 codons to specify each amino acid.
Since each codon consists of three nucleotides, multiply the number of amino acids (100) by the number of nucleotides per codon (3).
Use the formula: to calculate the total number of nucleotides required.
Conclude that the total number of DNA triplets in the sequence is equal to the number of amino acids multiplied by three.
